The Bible - Even if you arent Christian, great reading there
Gah, you got it before me
The Shannara series - Terry Brooks
The Art of War - Master Sun
Shakespeare
Death Gate Cycle - Margret Weis and Tracy Hickman
A Song of Ice and Fire - George R. R. Martin
Druids - Morgan (Llwynne?)
DIrk Pitt series - Clive Cussler
Various Titles - James Byron Huggins(though I haven't read them all, in my experience he is great)
Various Titles - Frank Peretti(again those I have read are wondeful)
These are in no order except when I thought of them.
Edit:
The Valley of the Dolls - If you havent read this, then your not very fond of reading, its the single highest selling novel of alltime
I am quite fond of reading, yet have never heard of this novel. What genre is it?
